Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Testing the Underlying Chemical Principles of the Biotic Ligand Model (BLM) to Marine Copper Systems: Measuring Copper Speciation Using Fluorescence Quenching [PDF]

, 2017
Speciation of copper in marine systems strongly influences the ability of copper to cause toxicity. Natural organic matter (NOM) contains many binding sites which provides a protective effect on copper toxicity.

The interplay among space, environment, and gene flow drives genetic differentiation in endemic Baja California Agave sobria subspecies

American Journal of Botany, EarlyView.
Abstract Premise Research on neutral and adaptive processes that lead to the divergence of species and populations is a crucial component in evolutionary and conservation genetics. Agave sobria is an endemic group of subspecies scattered on canyons along a latitudinal gradient and distinct environments of the Baja California Peninsula, Mexico.

Contribution to the assessment of the genetic potential of wild pear mother trees from the landscape of outstanding features ”Kosmaj” [PDF]

Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu
Native species of forest fruit trees represent an important component of biodi­versity, but are often threatened by the effects of various biotic and abiotic factors.

Phosphoinositide-signaling is one component of a robust plant defense response

Frontiers in Plant Science, 2014
The phosphoinositide pathway and inositol-1,4,5-triphosphate (InsP3) have been implicated in plant responses to many abiotic stresses; however, their role in response to biotic stress is not well characterized.

Floral scent of artificial hybrids between two Schiedea species that share a moth pollinator

American Journal of Botany, EarlyView.
Abstract Premise In flowering plants, pollinators' ability to recognize chemical displays of hybrids may erode reproductive barriers. Hybrids may produce novel or altered floral scent blends that are unattractive, or scents similar to either parent that remain attractive and promote backcrossing.

Deciphering fire tolerance of trees at the Amazonia–Cerrado transition by trait‐based approach: Implications from species to communities

American Journal of Botany, EarlyView.
Abstract Premise Understanding how fire impacts trees is essential for predicting the effects of novel fire regimes on plant diversity in the transition between the world's two most diverse biomes, the Cerrado and the Amazonia. Here we addressed knowledge gaps regarding physiological damage and mortality in transitional species within fire‐prone ...

Analysis of plant metabolomics data using identification‐free approaches

Applications in Plant Sciences, EarlyView.
Abstract Plant metabolomes are structurally diverse. One of the most popular techniques for sampling this diversity is liquid chromatography–mass spectrometry (LC‐MS), which typically detects thousands of peaks from single organ extracts, many representing true metabolites.
